||Approved||Revised riser diagram and scope of work submitted to show the change from dry pipe to a wet pipe system due to the attic space being converted to conditioned space.
Hydraulic calculations will not be revised for the following reasons:
1. Remote area was calculated at 2500 sqft for a dry system, which is greater than the minimum 1500 sqft required for a wet system.
2. The c-factor was caclulated at 100 for a dry system, where a wet system uses a smoother c-factor of 120.
These two things actually cause the hydraulcs to perform better than as calculated

The flushing and pressure test is to be witnessed and approved in writing by a member of the Colorado Springs Fire Dept.
ABOVE GROUND PIPING:
All piping and attached appurtenances subjected to system working pressure shall be hydrostatically tested at 200 psi or 50 psi in excess of the system working pressure, which ever is greater, and shall maintain that pressure without loss for 2 hours. Note - This is to include the piping between the fire department connection and the check valve. (NFPA 13:24.2.)
|FYI||(13) ELECTRICAL SUPERVISION REQUIRED:
All valves controlling the water supply for automatic fire sprinkler systems, fire pumps, tanks, water levels and temperatures, critical air pressures, and water flow switches on all sprinkler systems shall be electrically supervised. (2003 IFC 903.4)
An approved central station, remote station or proprietary supervising station as defined by national standards shall monitor this supervision.
PLEASE NOTE - Separately Fire Department approved plans and permits are to be obtained prior to the installation of the required sprinkler system monitoring system or fire alarm system.
A Knox Box is also required. Contact the CSFD for the information needed to order this key box.|

Along with the required exterior sprinkler system flow horn/strobe alerting device, an approved horn/strobe sprinkler flow alarm to alert the occupants shall be provided in the interior of all sprinkled buildings in a normally occupied location. (IFC 903.4.2.1)|
|FYI||(13) EXTERIOR NOTIFICATION:
An outside water flow alarm (horn/strobe) is to be installed within 20' of the fire department connection (FDC) to the building sprinkler system in a location that will be highly visible to responding fire crews. This horn/strobe is to activate ONLY on sprinkler water flow, not on general building alarms. (IFC 903.4.2.1) |
